thread-safe.

Remarks

Internal class used to provide implementation of ILogger interface. Applications should use LogManager to get logger instances.

This is one of the central classes in the log4net implementation. One of the distinctive features of log4net are hierarchical loggers and their evaluation. The Hierarchy organizes the Logger instances into a rooted tree hierarchy.

The Logger class is abstract. Only concrete subclasses of Logger can be created. The ILoggerFactory is used to create instances of this type for the Hierarchy.
